Faqs
13
What payment terms does CHZ Lighting accept for project‑based orders?
We normally adopt T/T payment term: deposit before production, balance before shipment. For large‑size municipal‑project orders, we can discuss payment term upon evaluation. Discuss payment requirement with our sales representative.
14
What information should I provide to get accurate lighting‑project quotation?
Please provide project location, required lamp model/power, quantity, target‑market certification requirement, installation‑condition and expected delivery‑time. Fill in above information, our engineer will prepare formal quotation quickly.
15
How to store spare‑part lamps in overseas project local warehouse?
Store lamps in dry indoor warehouse, avoid long‑term open‑air stacking. Keep original anti‑moisture packing material before installation to prevent internal condensation. We include spare‑part‑storage tips in user manual.
16
Are there any special maintenance notes for high‑mast lighting fixtures?
High‑mast lamps require periodic inspection of lifting‑system (if equipped), cable connector tightness and housing anti‑corrosion condition. High‑altitude operation must follow safety‑operation standard. [[Link‑High‑mast‑product]] We attach high‑mast‑lamp safety‑maintenance reminder.
17
What will cause smart‑street‑light LCU controller to go offline on‑site?
Common causes: power‑supply failure, signal‑obstacle interference, gateway‑network‑breakdown, controller hardware damage. Our technical team supports remote fault analysis. Provide platform‑alarm information for troubleshooting assistance.
18
For smart‑cloud‑managed street‑light projects, what daily‑operation work is required?
Monitor device online‑status on cloud platform, export energy‑consumption statistics, handle offline‑device alarm information, periodically check gateway‑network‑connection status. [[Link‑Smart‑solution‑page]] We offer platform‑operation‑training video document.
19
How to judge whether solar‑street‑light battery needs to be replaced on‑site?
Main symptoms: obviously shortened night‑working hours, insufficient brightness even under full‑sunshine charging condition. We provide simple field‑testing‑method guidance. Send us your solar‑lamp failure phenomenon description.
20
After multi‑year‑operation, can we replace only driver instead of buying whole new lamp?
For modular‑design lamps, driver can be replaced independently. For compact integrated‑structure lamps, whole‑lamp replacement will be required. We mark maintainability in each lamp datasheet.
21
What risks will long‑term over‑voltage bring to outdoor‑lighting lamp on‑site operation?
Continuous over‑voltage will accelerate driver aging and shorten overall lamp service life. SPD surge protection and grid‑voltage stabilization measures are recommended for poor‑grid‑quality sites. [[Link‑Blog‑surge‑protection]] We suggest voltage‑monitoring for unstable‑grid‑project sites.
22
Can you supply maintenance‑training documents for our local on‑site technicians?
Yes, we can provide English‑language maintenance manuals, fault‑check flow‑chart documents for your local‑technician training. Submit request for technical‑training‑material package.
23
If partial lamps fail in large‑scale project, what is your recommended troubleshooting workflow?
First confirm power‑supply & cable‑connection; collect failure‑lamp photos and site‑environment description; send information to our technical team for remote analysis. Please do not disassemble lamps without technical guidance.
24
What maintenance work should be done for solar street‑light systems every year?
Clean solar‑panel surface dust; check battery working status; inspect cable connector tightness; verify dusk‑dawn auto‑switch function. [[Link‑Blog‑solar‑troubleshooting]] Our manual contains solar‑lamp annual‑maintenance guidance.
